  • Miswire and reverse current protection

  • Surge protection


  • Use either a Tulip provided Factory Kit power supply or a regulated 24V input

Grounding and Earth Connections

  • Chassis (including the DIN mount) and 24V Return are internally connected

  • Optionally, pin 2 of the supplied 3-terminal power connector can be referenced to earth

  • Input banks A and B on the Gateway feature an additional grounding pin reference to the 24V return for convenience


  • In production, DIN rail should be held at earth potential.

  • Optionally, pin 2 of the supplied 3-terminal power connector can be referenced to earth.

User I/O

  • Two user buttons A and B can be used for device resets

  • Hold Buttons A and B for 5 seconds to perform a factory reset

  • Hold Button A for 5 seconds to enable the Tulip Access Point

  • Hold Button B for 5 seconds after a plug cycle to auto-enable Tulip remote support

  • One reset button (resets CPU)

  • Heartbeat/Alert LED for device diagnostics
